The booming use of mobile devices has skyrocketed Internet use to a completely new level, and today we take the Internet with us everywhere. We communicate and connect through social media, watch movies and listen to music online, do our banking and store our pictures in the cloud. In response, data centres of all sizes have sprung up around the world, and the servers within them generate lots of heat, which requires huge amount of energy to cool.

But cooling solutions – such as CRAC units and Kyoto wheels – have to contend with challenges including hot spots and peaks and troughs in demand, which affect their efficacy and efficiency. Alfa Laval and Dutch partner Boersema Installatie Adviseurs have come up with an unorthodox server room solution, Low-Speed Ventilation, that solves many of these challenges and helps keep the Internet cool.

More about LSV (Low-Speed ventilation) from Alfa Laval:

The slow-moving air and large cross-sectional area make the heat transfer very efficient. After a year-long study, we successfully developed steering algorithms to further increase the temperature of the air cooler water side. This adds sustainability to reliability, durability and energy-efficiency.” KEES BOERSEMA, BOERSEMA INSTALLATIE ADVISEURS

With LSV, we get a normal pressure in the entire room, still delivering the required amount of air. We don’t have to worry about the pressure at all, which is a totally new way of thinking.”MATS CARSELID, GLOBALLY RESPONSIBLE FOR DATA CENTRE COOLING SOLUTIONS AT ALFA LAVAL
